What is the result when a fiber segment has excessive attenuation?

When a fiber segment experiences excessive attenuation, it means that the signal is losing strength as it travels through the fiber. Attenuation occurs due to various factors, including scattering, absorption, and imperfections in the fiber. As light signals travel through the fiber, these factors can cause the intensity of the light to diminish, leading to a weaker signal at the receiving end.

This weakening can result in reduced data transmission quality, increased error rates, and possibly a complete failure to receive the signal, depending on how severe the attenuation is. Therefore, excessive attenuation directly correlates with a loss of signal strength, making the choice of a weakened signal the correct outcome.
